I assume you mean to use this on a single product’s page, right? If so, try this:
add_action('admin_head', 'wwc_my_custom_css');
function wwc_my_custom_css() {
if (!current_user_can('edit_pages'){
global $post;
$isProduct = $post->post_type == 'product'; // use the actual name for product
if ($isProduct ) {
echo '<style>
#mceu_27-body, #wp-content-editor-tools{
display:none !important;
}
</style>';
}
}
}
